GDVA-405 IEC Current Transformer Tester with PC Embedded CT PT Tester
Some key features and functions of a Transformer CT PT Tester:
1. CT Testing: The tester is capable of measuring the ratio, accuracy, and phase angle error of current transformers. It verifies whether the CT accurately converts primary current to secondary current and ensures that the CT operates within the specified accuracy limits.
2. PT Testing: The tester can also measure the ratio, accuracy, and phase angle error of potential transformers. It verifies whether the PT accurately steps down primary voltage to secondary voltage and ensures that the PT operates within the specified accuracy limits.
3. Excitation Testing: The tester can perform excitation tests to evaluate the magnetizing characteristics of CTs and PTs. This includes measuring the exciting current, saturation characteristics, and knee point voltage of the transformers.
4. Burden Testing: The tester can simulate various burdens and measure the secondary voltage or current of CTs and PTs under different load conditions. This helps assess the accuracy and performance of the transformers at different load levels.
5. Polarity Testing: The tester can determine the polarity of CTs and PTs accurately. This is important for correct and coordinated connection of the transformers in the electrical system.
6. Turns Ratio Measurement: Some advanced CT PT testers can measure the turns ratio of PTs, which is crucial for accurate voltage measurement and metering.
7. Data Analysis and Reporting: The tester often includes data analysis and reporting capabilities. It can store test results, perform calculations, generate test reports, and facilitate data management for future reference and analysis.
8. Safety Features: Transformer CT PT testers are designed with safety features to protect the operator and the equipment. These features include over-current protection, over-voltage protection, and grounding mechanisms.
